Serious Newbie questions. My bike's oil sits at full when it has sat over night. but once I get it running, the sight glass barely shows any oil at all and all I see is some oil foaming at the bottom of the sight glass. Is this normal? Sorry if this has been posted, but none of the posts was specific to this question (or at least that I found). Should I check my oil after it has sat over night, or should I check the oil after a ride (when it has had its chance to lube the gears up)?
I use regualr 10w40 oil, but from reading the posts, I might just try to use Motul 5100.
When should I be changing to synthetic? I've done my first oil change on my new bike at 1000km and now I have about 2300km.
